air pressure ??
When you guys change wheels or even just brands of tires, how do you determine what air pressure to run? Do you still go off of the factory recommendation or what? I know how I do it for cages, with the chalk line, but can't imagine that would work on a bike tire because of the shape....
I know that is an option, but I wanted to see if that is what you guys go off of or not. Especially since the bikes have different weights, etc.
I know metzler gives recommended tire pressures on their website. The ones stamped on the tires themselves are max pressure at max load, so I don't use that to determine running pressure. Though if I was completely in the dark on what to run, I'd probably take the max pressures minus a couple psi and see how they felt.

Go by what the tire manufacturer recommends. Another rule of thumb is that the tire pressure should be about 10% higher when warmed up from cold.
I've been feeling the temperature with my hand. It's important that the rubber gets warmed up enough so it will stick, but not overheat so that it gets slippery (and would wear out faster).

Under all circumstances, the tire pressure depends on the riding weight and the tire dimensions.
The pressure stated on the tire itself, is a recommended max pressure.
No matter what tire you put on, foolow the instructions from the bike manufacturer. From there, it´s possible to adjust a little both ways according to air- and road temperature, riding style and other stuff.
